Its a hardware issue, not a software issue that could be addressed with a firmware update. The best you can hope for is internal decoding of DTS-HD Master Audio and LPCM output via HDMI, which is how the PS3 currently handles TrueHD and Dolby Digital Plus. By the way, the PS3 already can decode and playback ALL Dolby codecs, either in 5.1 or 7.1 format. ......."

So it appears the TrueHD is internally decoded by the ps3 and then transported via PCM.

Goto information>audio input signal and it will show you whats coming in and what DSP (if any) is applied.

Regarding video, even with standard TV, if I adjust some video settings like brightness, contrast, etc, I see no change. Nothing happens.

If you selected uncompressed you are getting PCM and will only see multi-ch in or any postprocessing on top of it. Assuming you have the plyer correctly set to bitstream you need:

1) A disc with DTS-MA AND
2) Pick DTS-MA on the disc audio menu (it is typically NOT the default)

Ok, in the player's menu I selected uncompressed as it is the only other option beside standard DD 5.1. Would that be either DTS-MA or TrueHD? Sorry for the dumb question: is PMC a different signal from the before mentioned uncompressed DTS and Dolby?

Secondary audio is off.

Movie I have handy at the moment is a just released No Country for Old Man

I've always felt multiple side surrounds would be ideal if you had the room instead of dipole/bipole.
Are the delays in the Denon enough, or are you talking about something else?

Yes, you need to pick a movie with DTS-MA and pick it on the audio menu when playing or you will only see what you are seenig on the front panel. This is not a processor or a player issue. You need to pick a different disk and look at the lower back case to see what audio is supported.

The No Country uncompressed should be excellent audio, regardless of what the front panel says.

Keep it simple: PCM = DTS HD = TRU HD (all are equal)

DTS HD will show DTS HD ma on your receiver, TRU HD will show Tru HD and PCM will show multi ch in.

It is very confusing until once learn it, I know. But, The BD30 gives you an option to select PCM or Bitstream. So everyone here agrees that bitstream is the way to go. Ok. Then, while playing the selection the AVP displays PCM?! Now I understood that PCM is as good if not better the so much publicized Dolby TrueHD and DTS-MA. So why don't we see unpublicized the PCM as well?
Of course it is confusing.

Very much appreciated your replies.

DTS-HD MA and TrueHD are both compression codecs. When both DTS-HD MA and TrueHD are uncompressed they are PCM. When your Denon receives a DTS-HD MA signal it will display it on it's front panel. The Denon takes the Compressed DTS-HD MA signal and decodes it into a Uncompressed PCM signal to feed it's DSP and DACS.
When a disc has a Uncompressed PCM 5.1 or 7.1 soundtrack it just means they had enough room on the disc that they did not need to compress it with either DTS-HD MA or TrueHD.

Think of it like a computer program. When a file is very large it is often zipped (compressed) so it is smaller to send, when it arrives at the destination computer it then needs to be unzipped (uncompressed) so that it is usable.

It is a very simple process that can confuse a lot of people if they over think it.
